l Letters Patent No. 112,332, `dated March 7, 1871.

4 Beit known that I, THOMSON FREEMAN, of West- `e1d,in the4 conntyof Clark and -State' `of Illinois, have, `as I believe, invented new `and nsefnlmprove ments finOhurns for the ButterDairy; and VI do hereby declarethe following to bea full and exact de- \.sc11'p,tion of the same, referencebeing had to the "drawings that 1 accompany speciiication.` H

Figure 1, view of the churn asit stands ready for i use. 1 l

fliigure 2,. view of the interior parts, detached. The object of my invention is to produce the greatl est amount of violent agitation of the cream for any r given force; employed, and in such manner as not to `pound or strkejtbe cream'` forcibly, thns avoiding the "l mashing Of `the granules, which mashing always ren- ,.ders buttersalvey and like lard in spreading. A represents an ordinary upright cream-box, and i wnay be square, cylindrical, or of other convenient l crm. i

B,base, towhich the box Amay be' attached in any suitable way -to retain* it in place.

C, aist-andard, rising from one end of the base B.

D,'a frame, the style and arrangement of which `may be seen' inwfig. 1 of the drawings.

` l E, drum-dash,` which is operated through the fcame D, as fully explained hereinafter. `f

` l f, a strap arranged to extend from'the lower end of the bent bar of the frame I), at c, passing once around the drum y to thetlower end of the bar-h, where it fastens over a pin and may b e drawn tightly or left I more loosely,.as maybe required. v

`opening at itslower. end `for the upper, end'of the dash-rodj, which is fastened in place by the pin u.

t 1t,`disk of the dasher, perforated with more or less holes. i r

and form a part of this IMPROVEMENT IN CHURNS.

The Schedule referred to these Letters Patent and making part of the same.

The joint of the rod fi, with the bent bar of the frame at fw, is a flexible universal one, to allow the outer end of the frame to be worked up and down, as indicated by the dotted lines in red in fig. l. The end ofthe bent bar at the top of the standard O turns on the pin x.

The operation is as follows; l

Force applied to the working-handle o, to lift and depress it in rapid succession, n otl only raises anddepresses the dasher within the churn-box, but also,

through the action of the strap f, rotates it horizontally backward and forward very rapidly. l

Thus, while thebottom plane of the disk k cannot be brought forcibly onto the bottom ofthe churn-box to mash the granules, the height to which the dasher is. brought is easily regulated tov terminate below thc surface of the cream, so it 'will not strike a blow in descending andn break granules in that Way.

.The violent agitation into which the cream is thrown by the combined action of the alternating vertical motion an thereciprocating rotary motion of the dasher wears out the skinsidthe little sacks that hold the granules of butter in an incrcdiblyshort space of time, producing butter of very superior quality, being in no Way injured by -violent concussion orpose of obtaining a combined reciprocating and vrotary motion ofthe flasher, substantially as described.

' In testimony whereof Iha've signed my name'to this speeiiication in the presence of two subscribing witnesses.

, THOMPSON FREEMAN.
